IMPROVED REGISTER FOR GAS AND WATER METERS.

Specification forming part of Letters Patent No. 37,832, dated March 3,1863.

To aZZ whom it may concern:

Be it known that I, JOHN J. SQUIR-E, of the city of New Haven, in thecounty of New Haven and State of Connecticut, have invented a certainnew and useful Improved Register for Gas and Water Meters 5 and I dohereby declare that the following is a full, clear, and eXactdescription thereof, reference being had to the accompanying drawings,and to the letters and marks thereon.

My invention has for its object indicating and registering the quantityor amount of gas or oth er tluid which shall have passed through themeter with perfect accuracy and relia bility 5 and it consists incombining with the toothed wheels, or movements,77 as commonly called,of the indicating portion of the meter certain cams and levers, or theirequivalents, so being operated that certain figures are shown orexposed, and certain other figures not shown or exposed, wherebyconfusion is prevented and the registering simplified and perfected.

Of the drawings forming part of this speciii cation, Figure lis afrontelevation of the registering case orbox, Fig. 2bein g a front view withthe outer plate removed, so as to show the interior means or movements,Fig. 3 being a top view or plan; Figs.4 and 5, a plan and view bysections of the revolving dial and cam combined.

In each of these figures like parts are indicated by like letters andmarks.

The outer plate or cover, A, has openings l 3 5 immediately in front ofeach dial,which openings are equal to the distance of consecutivefigures. The small dial, a, havin g a measurement of iive, is used onlyas evidence of the meters working.

B B B are revolving disks or dials having the figures from l to l()arranged equidistant around their faces. These dials are firmly securedto the end of spindles, carrying their respective toothed wheels o c c,which work in train, and are propelledby the movements connected withthe passage of the gas or other fluid through the meter. On the hack ofthe dials B B are cam-grooves, as shown by Figs. 4 and 5, or cam iianges or projections. If the grooves be used, a pin on the end of thelever iits into the groove, and if the projections be used, the end ofthe lever is slitted to fit the iiange or projection.

Plates D D, when secured together by braces e e e, constitute the framewhich contains the working parts. The levers l 2, Fig. 2, are connectedto the frame D by pins a: :0, which serve as fulcrums. One end of thelever is connected to the cam-iiauge or fitted into the camgroove, whilethe other end is attached to the shields 3 e 5. These shields move upontheir pivots freely, and are arranged in front of each respective dialand back of the openings l 3 5 in the cover A, so as to con tract theseopenings at the right or the left hand, as required. Lever l isconnected to dial B and its cam, and to shields 3 and Li, as shown byFig. 2 of the drawings, and lever 2 is connected to dial B and to shield5.

Now, on motion being given to the movements or train of wheels by thepassage of gas or other iiuid the dials B B B are made to revolve. Asthe dials are revolved, the levers l 2 are acted upon the cams and givemotion to the shields 3 A 5. Dial B revolved once round would indicate apassage or flow of gas equal to av quantity of one thousand, which wouldbe recorded upon dial B, next in value, and dial B having made onerevolutiomwould indicate a quantity passed equal to ten thousand, whichwould be recorded upon dial B, and so on as to the number in the train.

As dial B revolutions have to be recorded by the dial B, and so on to B,it necessarily follows that the gures will notonly be correct, but willbe clear and distinct and be read without confusion or mistake. Thisresults from the simultaneous action of the dials, cams, levers, andshields, the latter hiding the receding figure and exposing theadvancing figure as the change takes place from a lower to a higherdenomination, and hence the reading of the register is rendered simple,easy, and free from confusion or error.

By referring to Fig. 2 of the drawings it will be seen that each dialstands upon the point of change simultaneously, which only occurs onstarting anew at a measurement 0f one hundred thousand. B being upon thepoint of change, lever l is acted upon by the cam, and the shields 3 and4 are moved, 3 to liide the iigure 9 and e to expose the 0 in dial B,while, at the same time, the 9 on dial B is hidden by the projectionupon the dial B. B, being also upon the changelever 2, is also actedupon by its cam, which simultaneously moves shield 5, hiding the ligure9 and expos- The abovedescribed arrangement of the ing lhe 0' in B. Aseach revolves their shields cams, levers, and shields when applied togas are reversed, and the openings in Jche coverA or Water meters, asand for the purpose herein are left full, so that each recording numberis set forth.
